The iconic scene from Jurassic Park came in the car where the glass of water resonated with the approaching footsteps of the T-Rex (spoiler). The original scene was done according to web blogs by someone carefully boinging a musical string attached to the support for the glass–they had tried other methods but this was the […]
Solar energy is renewable, free, widely available and clean form of energy. It is considered as a serious source of energy for many years because of the vast amounts of energy that is made freely available, if harnessed by modern technology. Many people are familiar with so-called photovoltaic cells, or solar panels, found on things

Description This is a 1×1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto

Bismuth is considered as a āgreen-elementā and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of theĀ University of Cambridge and the United States developed theoretical and experimental methods to show that bismuth, which sits next to lead (Pb)Ā on the periodic table, can be used to make inexpensive solar cells.

Researchers developed a multijunction solar cell on a GaSb substrate that can efficiently convert the long-wavelength photons typically lost in a multijunction solar cell into electricity. This prototype cell has an efficiency of 44.5% which is higher than conventional solar cells. A GaAs-based cell is stacked mechanically with the GaSb-based materials to create a four-terminal,

Yesterday, I builtĀ aĀ very simple DIY solar-powered USB charger for my TP-linkĀ 10400mAh USB Power Bank.Ā All I needed was a 6V/3.5W solar panel and the TD1410-based 5V buck converter module. I bought both of them on Aliexpress for less than $8. It was one of the easiest projects I built. All I needed to do was to
